Weird urine smell and metallic breath after 1 week of keto — is this normal?

Hi everyone, I’m new to keto and I’m about 1 week in. I’ve noticed a couple weird things and I’m wondering if they’re normal.

My urine smells really strange, almost like cheap plastic or something synthetic, and my breath has this metallic/chemical taste, even when I brush my teeth.

I’m drinking about 3 liters of water per day, so I don’t think I’m dehydrated.

Otherwise I feel okay, but the smell and taste are pretty noticeable and kind of odd.

Is this something that happens when you start keto? Has anyone else experienced this?
